As shown in the drawings:

The reference numeral 1. indicates a large easing, storage tank or primary gas reservoir, having an aperture in each end there of in which is removab-ly threaded a plug 2, to close the same. An aperture 3, is pro "ided in the rear wall of the casing 1, the nun-gin of which is bent outwardly to form a collar 4:, in which is removably threaded.

a large plug 5, to close the aperture 3. Integrally formed on the front wall of the casing 1, and in communication with the interior thereof. is a small casing or secondary gas reservoir 6, having an aperture 7. 1n the outer end wall thereof, for a purpose hereinafter described. The top of the small casing 6, comprises two parallel grooved sections 9, are a plurality of parallel crosspieces or bars spaced a short distance apart to form a. long narrow grid or generating burner 11, between the troughs 8, forming the starting burner.

An aperture or oil gas opening 12, is formed near each end of the top wall of the casing 1, and integrally formed or rigidly secured around each aperture a short distance'from the periphery thereof to aiford a shoulder or seat 13, is a ring or collar 14.

A cooking burner is rcmovably mounted.

over each of the oil-gas openings 12, and comprises a stand or feed pipe 15, the lower end of which is adapted to rotatably and removably fit in one of the collars 11, and seat or rest upon the shoulder 13, thereof. The upper end of each feed pipe 15, is rigidly secured to or expanded into a suitable gas inlet opening provided near the outer eriphery of a bottom or base plate 16, having a peripheral notch or groove 17, therein to permit a burner casing 18, to seat upon said base plate, as clearly shown in Fig. 8. The top Wall of each burner casing 18, has a plurality of small gas apertures 19, therein. Rigidly secured upon the upper rim of each burner casing are a number of equidistantly spaced arms or supports 20, to hold a baffle plate or stove plate 21, in position above and arallel to the top of each burner casing 18. flach b-atlle plate is provided with a large central opening 22, surrounded by a pinrality of small apertures 23, to permit the oil-gas flames to pass therethrough to heat a cooking utensil placed upon the baflle plate. Pivotally mounted upon each of the base plates 16, by means of a pin 21, to form a valve is a. shutter. regulating or controlling disk 25, provided with a handle 26,

which extends outwardly through a suitable slot in the burner casing 18, to afford a means for swinging the disk 25, to regulate the flow of Oil-gas from the casing 1, into the cooking burners.

Integrally formed or rigidly secured to the bottom of the casing 1. is a fuel mixing or carbureting pipe 2 the inner end of which is bent or cur /er. upwardly to communicate with the interior of said casing through a suitable fuel inlet opening 28, formed in the bottom of the casing. Secured within the mixing pipe 27, is a tube 29, the outer diameter of which is less than the inner diameter of the pipe 27. Integrallv formed on each end of the tube 29, are a plurality of lugs 30, which contact the inner surface of the pipe 27, to hold the tube 29, spaced from the pipe 27, and afford a passage 31, between said pipe and tube. Secured over the outer end of the mixing pipe 27, is an air intake elbow 32, having an aperture 33, in the outer curved portion thereof.

Engaged in the aperture 33, is the tapered or inner end of a nozzle 34, having a small longitudinal passage 35, in the inner end thereof which communicates with a large longitudinal threaded passage 36, to afford a valve seat 37, at the point where said passages join. Adjustably threaded in the passage 36, is a threaded shank or screw 38, having integrally formed on one end thereof a valve rod 39, the outer end of which is tapered and adapted to seat in the valve seat 37, to close the oil-gas outlet passage 35, when said valve rod is moved inwardly .by the rotation of the screw 38, which may be actuated by a rod 10, integral with the other end of the screw 38. Said rod 10, projects through an apertured cap 11, threaded upon the externally threaded outer end of the nozzle 31, and through the outer wall 12, of an auxiliary wick starting burner 43, and is provided with a handle 11, conveniently loeated to permit ready adjustment of the oil-gas inlet valve mechanism. Integrally formed or rigidly secured to the outer tapered end of the valve rod 39, and extending through the oil-gas outlet passage 35, is a cleaning blade or knife 45, adapted to be rotated within said passage 35, simultaneously with the actuation of the valve mechanism by the handle 41, to scrape the walls of said passage 35, to keep the same clean from dirt, carbon or other clogging substances.

Integrally formed centrally upon the upper side of the nozzle 34, and at right angles thereto is an inclined generating pipe 10. having a passage 47, therein, the lower end of which communicates with the nozzle passage 36, while the upper end thereof communicates with a passage at right angles thereto formed axially through an externally threaded arm 18, integrally formed on one side of the upper end of the auxiliary oil gas generating pipe 46. Threaded upon the arm 48, is one end of a long slightly inclined main oil-gas generating pipe or tube 4-), which extends lougitudinally of the device above the generating burner 11, and between the troughs 8. of the starting burner. and is rigidly held in position by supporting brackets 50, secured upon the exterior of the casing 1. Disposed retreat? longitudinally within the main generating tube 49, are a plurality of concentric spiral springs or coils 51, which are held therein by means of a passaged coupling or conmotor, the inner end 52, of which is enlarged and threaded to thread into the open end of the tube 49, while the other end'53, is separated from the enlarged end 52, by anut 54, and is threaded to receive the end of a kerosene or other hydro-carbon fuel sup ply pipe or hose thereon.

Threaded into the aperture 7, of the small casing 6, is a threaded passaged arm 55, integrally formed on the inner side of an inclined pipe burner 56, having a plurality of apertures 57, therein. is disposed parallel to and below the inclined generating pipe 46, to permit oil-gas flames flowing from the apertures 57, to heat the pipe 46, during the process of oil-gas generation.

Rigidly secured below each end of the casing 1, and extending laterally beyond each side thereof is a metal strip or crossbar 58,

the ends of which are bent downwardly at.

right angles to form brackets or arms 59,

having a threaded aperture near the lower and to adjustably receive an adjusting bolt 60, threaded therein. Disposed flat against the outside of each of the arms 59, is a standard or leg 61, provided with a vertical slot 62,in the upper portion thereof through which one of theadjusting or looking bolts 60, projects to permit the legs 61, to be adjusted to support the device at different heights.

lln the modified form of cooking burner shown in Fig. 14, the numeral 62, designates a stand or feed pipe the upper end of which is expanded into a suitable aperturedisposed at one side of the bottom or base plate of the lower section 63, of a burner casing. Mounted upon the rim of the lower section 63, is a partition plate 64, forming a lower chamber Y65, and having a large central opening 66, therein over which an eX- ternally operated shutter or controlling disk 67, pivotally mounted upon said partition plate 64, is adapted to be moved to regulate the opening from said lower chamber 65, into an upper chamber 68, provided by an alpper burner section 69, seated upon the partition plate 64, and having a plurality of burner apertures 70, in the top wall thereof. This arrangement permits the oilgas mixture entering at the bottom of the lower chamber 65, to pass and expand into said lower chamber and then pass upwardly through the valve opening 66, so that the oil-gas entering the upper chamber 68 may flow out of all of the burner apertures 70, under equal pressure.

In the modified form of carbureting mechanism shown in Fig. 15, the construction of the carbureting or fuel mixing pipe Said pipe burner and the air intake elbow is the same as that disclosed in Fig. 6. The mixing tube 29, however is replaced by a large mixing tube 71, provided with outwardly bent integral lugs 72, to hold the same spaced from contact with the inner surface of the pipe :27, to afford an air passage between the pipe 27, and the tube 71. The inner end of the tube 71, is tapered or restricted to slightly coinpress the oil-gas passing therethrough so that the oil-gas may expand in the curved end of the pipe 27, and mix with air entering into said pipe from the passage between the pipe and said tube 71. I Disposed longitudinally Within the tube 71, is a smaller mixing tube 73, provided with integral lugs 74, to hold the same spaced from the inner surface of the tube 71, to afford an air passage between the tube 71 and the tube 73, whereby the air and gas entering the carbureting chambers within the tube 27 formed by the concentric arrangements of the tubes 71 and 73, may be thoroughly mixed before entering the casings 1 and 6.

The operation is as follows:

Kerosene or other suitable hydro-carbon fuel is supplied to the burner through the main generating or supply pipe 49, passing around the spiral concentric springs 51, and into the passage 47. The wicks 1(), disposed in the troughs 8, of the primary starting burner, and a wick 75, of the secondary starting burner 43, are saturated with kerosene and lighted, the heat therefrom tending to rapidly heat the pipes 46 and 49, and the springs 51, thus causing a primary generation of oil-gas, in said pipes, which gas passes through the passage 47, into the chamber 36 of the nozzle 34, the tapered end of which projects into the aperture 33, of the air intake elbow 32. By turning the handle 44, the valve rod 39, is unseatcd permitting the oil-gas to pass through the narrow passage 35. The air flowing into the .burner through the open end of the intake elbow 32, flows into the mixing tube 29, with said oil-gas, and through the passage 31, surrounding the tube 29, into the chamber in the curved inner end of the mixing pipe 27, where the air from the passage 31, further mixes with the already partially mixed oil-gas and air flowing from the interior of the mixing tube 2.), into the curved portion of said pipe 27. The oil-gas thus thoroughly mixed with air passes upwardly through the opening 28, into the primary fuel gas chamber within the fuel gas reservoir or storage casing 1. and into the secondary fuel gas chamber within the fuel gas storage casing 6.

From the gas chamber within the casing 6, the fuel gas thus generated by the start ing burners flows through the slots of the generating burner 11, and out of the apertures 57, of the inclined pipe burner 56. and

is ignited thus atiording a means for continuing the heating of the gas generating pipes -19 and i6. and the springs 51, to generate more gas by the burning of oil-gas already generated thus permitting the process of oil gas generation to continue, after being started by the starting burners which of course go out after the kerosene with which the wicks are saturated is burned up.

To utilize the burner as a cooker the fuel gas from the gas chamber within the casing 1, flows upwardly through the pipes 15, and into the interior of the burner casings 18, the shutters having been opened by means of the handles 26. From the casing 18, the gas escapes through the apertures 19, and is ignited. the flames passing through the openings Q2, and apertures 23, heating the bafiie plates :21, and any cooking utensils which are placed thereon. It will of course be seen that the flow of fuel gas into the cooking burners may be regulated by means of the shutters 25, and that the flow of oil-gas into the mixing chambers of the pipe :27, may be regulated or entirely shut off by turning the handle 41, thus operating the controlling valve within the nozzle 34. The narrow passage 35. of the nozzle 3-1, is always kept clean from dirt or carbon by means of the knife blade -15, which scrapes the walls of the passage each time the handle H, is actuated.

\Vhen it is desired to shut off the burner the gas valve 39, is closed by turning the handle it, thus shutting off the gas supply. The burner is then allowed to burn until the fuel gas supply in the gas chambers is used up.

The plugs 2 and 5, provided to fill the apertures in the casing 1, may be removed atany time to permit at ditional cooking burners to be attached. It will be noted that the legs 61,f0r the burner are adj ustably mounted to permit the burner to be raised or lowered to fit in an ordinary kitchen coal range or cook stove, with the legs resting upon the coal grate. The cooking burners which are adapted to be rotated in a horizontal plane, may be disposed so that the battle plates secured thereon will fit in the openings in the top of the range or stove.

The cooking burner shown in Fig. 14, is mounted similar to the cooking burners shown in Fig. 1. The fuel gas entering through the pipe (32, disposed to one side of the burner casing, first enters the lower chamber 65, and then passes upwardly through the central opening 66, when the shutter 67, is open into the upper chamber 68, thus permitting the fuel gas to expand and flow out of all of the apertures 70, under an equal pressure to afford a uniform flame.

In the carbureting or mixing mechanism shown in Fig. 15, the concentric arrangement of the spaced tubes 71 and 7 3, within the mixing pipe 2?, permits the air and oil gas from the intake elbow 32, and from the gas nozzle 31, to become thoroughly mixed at different points of its passage through said mixing mechanism before passing into the fuel gas chambers of the casings 1 and t3.
